Inventor: NISHIKAWA KIN
IPC: H04N5/76
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a maximum luminance of an accurate video signal by giving a signal switching the state of a buffer and the state of maximum value detection to two multiplexers. CONSTITUTION:When the maximum value detection mode is selected by a video/peak switching signal generating means 113, a capacitor 103 is connected to the emitter load of a transistor (TR) 101 by a multiplexer 106 only in the timing of an effective pattern by an effective pattern signal generated by an effective pattern signal generating means 112. The potential across the capacitor 103 is kept to a potential representing the maximum brightness of an inverted input video signal by a diode located across the base and emitter of the TR 101. The voltage is given to a buffer amplifier 104 at a high impedance and outputted at a low impedance and fed to the base of an emitter follower composed of a TR 107 with different polarity to that of a 1st TR 101 and outputted from the emitter with a low impedance. Thus, an accurate maximum value is obtained.

Abstract: PURPOSE:To simply increase the alloying element content of a molten Al alloy by allowing a liq. phase of an Al alloy having a reduced alloying element content to coexist with a solid phase contg. a large amt. of the alloying element and rotating an internal cooling type cooling body in the liq. phase. CONSTITUTION:A molten Al alloy 6 is poured into a crucible 2 in a treating furnace 1 fitted with a heater 3. In the molten Al alloy 6, a liq. phase having a lower alloying element content than the original Al alloy coexists with a solid phase made of an Al-alloying element intermediate phase and having a higher density than the liq. phase or a solid phase of the alloying element having a higher density than the liq. phase. The molten Al alloy 6 is held in the coexistent state and a cooling body 4 is immersed in the alloy 6 and rotated while cooling the alloy 6 from the interior. The solid phase is moved away from the cooling body 4 by centrifugal force and an Al alloy contg. a small amt. of the alloying element is crystallized on the peripheral surface of the cooling body 4 to form an Al alloy ingot I. This ingot I is pulled up together with the cooling body 4 and recovered. The alloying element content of the residual molten Al alloy 6 is increased.

Filed: 1986-12-30
Abstract: PURPOSE:To improve reception sensitivity and an error rate by converting a digital electrical signal to an optical signal after superposing the signal on a carrier wave, then transmitting the optical signal, and eliminating the carrier wave, on the reception side, after converting the optical signal to an electrical signal to reproduce the digital electrical signal.

Title: Freely extendable and contactable ski stick
Inventor: KANETANI YOSHICHIKA
IPC: A63C11/22
Filed: 1988-12-12
Abstract: PURPOSE:To freely adjust the length of a ski stick matching the height of a user, the angle of a sliding slope or the change of the sliding slope by movably coupling a grip thread part and a fixed screw, for which a thread is provided to match to the thread in the inside of a stick shaft thread part, and further providing a scale in the outside of a stick shaft part. CONSTITUTION:Since a fixed screw head part 13 in a size not to pass through a hole 6 is provided in the upper part of a fixed screw 4, the length is adjusted up and down for a stick shaft thread part 12 and a grip thread part 10 when the stick shaft thread part 12, grip thread part 10 and fixed screw 4 are revolved. Then, the fixed screw 4 fixes or calces this length. The stick shaft thread part 12 of a stick shaft 1 and the grip thread part 10 of a grip part 2 are revolved and the length is adjusted with no step suitably for the height of the user. Then, this length is fixed by the screw 4. Thus, for a person not to make progress even with practicing hard with the stick which is not matched to the person, when it is caused by the length of the stick, the suitable length can be naturally known by slightly changing the length at the site of practice. Accordingly, not only the most efficient training way can be obtained but also it is not necessary to buy the new stock.

Title: Character output system
Inventor: SAGA KAZUSHIGE
IPC: G06F3/12
Filed: 1986-12-29
Abstract: PURPOSE:To shorten the access time of a dynamic RAM and increase overall printing speed relatively inexpensively, by reducing the number of accesses through multiplying the memory width of one address, and converting the direction or size of a character pattern through combining a process for returning the memory width of one address to an original value. CONSTITUTION:For example, character patterns are so stored that a memory width equal to two times a raster width can be accessed with one address. The character patterns for one line which are read from a character pattern memory 10 in a form 1 are sequentially sent to a memory width converting circuit 21, where the memory width is converted to a form 2, and the character patterns thus processed are stored into a pattern buffer 22. The character patterns are rotated by 90 deg., thereby converting the patterns in a form (a) into the patterns in a form (b). The character patterns in the form (b) obtained by a change in direction are once stored into a pattern modification transferring circuit 23. Each raster pattern is sent to a raster buffer 24 comprising three raster memories having a doubled memory width, and the raster patterns are sequentially developed and stored into a bit map memory 12.

Title: Power supply device for wire electric discharge machine
Inventor: FUTAMURA SHOJI
IPC: B23H7/10
Filed: 1986-12-27
Abstract: PURPOSE:To improve the machining efficiency and the availability and to enable highly accurate machining, by providing a fusing section and a solidifying section for containing a low melting point alloy in a power supply case, and supplying power to a wire electrode through the low melting point alloy being held in fused condition. CONSTITUTION:A fusing section 4 and a solidifying section 5 for containing a low melting point alloy 8 are arranged in a power supply case 3 in the traveling direction of a wire electrode 1, then temperature gradient is set toward the solidifying section 5 and power is fed to the wire electrode 1 through the low melting point alloy 8 being held in fused condition. Consequently, the contact area is increased to enable supply of large current thus improving electric discharge machining efficiency considerably. Since large part of the low melting point alloy 8 contacting with the wire electrode 1 is fused or semi-solidified, frictional force is quite low and replacing frequency due to abrasion is reduced considerably thus improving the availability remarkably. Furthermore, lateral pressure is not required for the wire electrode 1, thereby the wire electrode 1 is not distorded nor deformed thus enabling highly accurate machining.

Abstract: PURPOSE:To obtain an image fiber having fixed intervals of picture elements by a simple method. CONSTITUTION:A quartz rod previously doped with fluorine is prepared. A great number of holes are bored in the length direction of the rod at equal intervals through the rod by an ultrasonic boring method.
